Everything shaping
the world of cooling.
Technology, companies and events worldwide
Since 2013, Peter Riedel GmbH has used Daikin refrigeration systems to cool the in-run surfaces of ski jumping complexes. The cooling capacity of the units is 16–25 kW, and operating parameters are adjusted remotely.
As inverter-driven and cold-climate heat pumps hold capacity into single-digit outdoor temperatures, manufacturers say the gas-furnace switchover point in dual-fuel systems must be set per application rather than by a universal rule. Daikin, Midea, Lennox, and Rheem outline how replacement cycles, evolving controls, and local utility economics are reshaping how contractors design and sell these systems.
Daikin Europe has commissioned Europe's first CO2-based VRV system at a Denns BioMarkt supermarket in Wiesbaden, Germany, integrating it with propane-based built-in refrigeration equipment under a unified BMS control. The CO2 VRV range currently features a single 10 HP outdoor unit; scaling across the full VRV lineup and chillers is planned for 2028.
D60-W combines liquid and air cooling with chillers, dry coolers and coordinated controls.
